Abstract: A user interface apparatus and method of using a touch screen are provided. The apparatus includes a touch screen division unit for dividing a screen area of the touch screen into zones, an allocation unit for allocating a user interface unit to each of the zones and a plurality of user interface units for sensing job commands input through the zones according to the allocation result of the allocation unit, wherein an operation corresponding to each of the sensed job commands is performed. Accordingly, since a plurality of users can simultaneously use an image-forming device by dividing the screen area of the touch screen into two or more zones, job processing time can be reduced, and a usage rate of a high specification image-forming device can be increased.

Abstract: An apparatus and method for treating wastewater are provided. The method for treating wastewater includes: a pre-treatment step of removing impurities contained in high concentration wastewater and crushing the impurities using a crusher; a first aerobic treatment step of supplying wastewater containing organic acids to a first aerobic tank and injecting air to the first aerobic tank to be aerobically treated; an anaerobic treatment step of supplying the wastewater, from which excess organic acids are removed by the aerobic treatment, to an anaerobic tank to be anaerobically treated; a degassing step of supplying the wastewater treated in the aerobic and anaerobic treatment steps to a degassing tank to remove air and gas; and a post-treatment step of precipitating the wastewater aerobically treated using a solid-liquid separation tank, a pressure floatation tank or a precipitation tank.

The apparatus and method comprise storing a specific scanning area input by a coordinate input means of the flat-bed type scanning apparatus; checking whether scanning is started; if the specific area is scanned, measuring a document size by performing scanning and storing the same; calculating an area to be scanned from the stored scanning area and the document size; and performing scanning for an area to be scanned.

Abstract: A facsimile re-transmits a received facsimile message to another subscriber without degradation of image quality. The facsimile includes first and second memories. The first memory stores the facsimile message received from a calling facsimile, receiving information for the facsimile message, and a selection number for selecting the received facsimile. The second memory stores facsimile numbers for subscribers to which the received facsimile is to be re-transmitted. At the user's request, the facsimile dials the facsimile numbers stored in the second memory to re-transmit the received facsimile message stored in the first memory to the subscribers.
